Description

Technical Field

[0001] This utility model relates to the field of harvester blade height and angle adjustment technology, specifically a harvester blade height and angle adjustment device. Background Technology

[0002] As we all know, in modern agricultural production, harvesters are key equipment for achieving efficient crop harvesting. Their performance directly affects the efficiency and quality of agricultural production. In order to ensure that harvesters can achieve good harvesting results under various complex agricultural conditions, the blades must be able to flexibly adjust their height and angle. If the blade height is set improperly, too high may cause the crop stubble to be cut too high, resulting in food waste, while too low may cause soil to be rolled into the harvesting system, damaging the blades and machine parts, and affecting subsequent land preparation work.

[0003] Currently, some traditional adjustment devices use manual adjustment, which is cumbersome and requires operators to frequently stop the machine to make adjustments. This seriously affects the continuity and efficiency of harvesting operations. Moreover, manual adjustment makes it difficult to achieve precise height and angle control, and it is often unable to adapt to complex and ever-changing agricultural conditions.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] See Figures 1-5 A harvester blade height and angle adjustment device includes a harvester blade 1, a mounting plate 2, a height adjustment component 3, and an angle adjustment component 12.

[0029] Mounting plate 2 is fixedly installed on the side of harvester blade 1, providing a mounting base for height adjustment component 3 and angle adjustment component 12, serving as a connection and support, and ensuring that each adjustment component can be stably installed on harvester blade 1 and work together.

[0030] The height adjustment component 3 is installed on the mounting plate 2 and is mainly used to adjust the working height of the harvester blade 1. The support column 4 is rotatably set on the top of the harvester blade 1. A sliding column 5 is slidably set inside the support column 4. The sliding column 5 can slide up and down inside the support column 4, providing a space for adjusting the height of the harvester blade 1. By changing the position of the sliding column 5 inside the support column 4, the height of the harvester blade 1 can be adjusted to adapt to crops of different heights. A vertical plate 6 is fixedly set on the mounting plate 2. A support column 7 is fixed to the side of the vertical plate 6. A sliding frame 8 is fixed on the support column 7. A slider 9 is slidably set inside the sliding frame 8. A connecting block 10 is fixed to the side of the slider 9. The connecting block 10 is fixed to the sliding column 5. This structural design connects the sliding of the sliding column 5 with the sliding of the slider 9 inside the sliding frame 8, so that the operation of the slider 9 can be transmitted to the sliding column 5, thereby realizing the adjustment of the height of the harvester blade 1. The sliding of the slider 9 inside the sliding frame 8 is restricted to a certain extent, ensuring the stability and accuracy of the adjustment process.

[0031] The drive assembly 11, which is fixedly installed on the vertical plate 6, is the power source for pushing the slider 9 to slide within the sliding frame 8. By transmitting power to the slider 9, the slider 9 moves up and down within the sliding frame 8, thereby driving the sliding column 5 and the harvester blade 1 to move up and down, achieving precise height adjustment. The angle adjustment assembly 12 is installed on the mounting plate 2. Its function is to adjust the angle of the harvester blade 1. During harvesting operations, different crops and terrains may require the harvester blade 1 to work at different angles.

[0032] The angle adjustment component 12 can adjust the angle of the harvester blade 1 to better adapt to actual working needs and improve harvesting efficiency and quality. For example, when harvesting crops that grow at an angle, by adjusting the angle adjustment component 12, the harvester blade 1 can maintain a suitable angle with the stem of the crop and cut more effectively.

[0033] First, refer to Figure 2 and Figure 3 In this embodiment, the drive assembly 11 includes a fixed base 13, which is firmly fixed to the side of the vertical plate 6, providing a solid mounting foundation for the entire drive assembly 11. A first gear 23 and a second gear 14 are rotatably mounted on the fixed base 13, and the two mesh with each other. The number of teeth of the second gear 14 is greater than the number of teeth of the first gear 23. This difference in the number of teeth constructs a gear reduction transmission system. In mechanical transmission, the gear ratio determines the speed ratio. When the first gear 23 rotates at high speed under the drive of the motor 25, it can transmit power to the second gear 14 through meshing with the second gear 14, while making the second gear 14 rotate at a relatively low speed. The advantage of this reduction transmission is that it can increase the torque output, so that the subsequent transmission components can obtain greater power, thereby more stably pushing the slider 9 to move and realizing precise adjustment of the height of the harvester blade 1.

[0034] The slot plate 24 fixed on the mounting plate 2 provides a mounting position for the motor 25. The output shaft of the motor 25 is tightly fixedly connected to the first gear 23. When the motor 25 is powered on and started, the output shaft starts to rotate, directly driving the first gear 23 to rotate synchronously. As the power source of the drive assembly 11, the stability of the speed and torque of the motor 25 directly affects the working performance of the entire drive assembly 11. By directly connecting the motor 25 to the first gear 23, the energy loss in the power transmission process is reduced and the transmission efficiency is improved.

[0035] The second gear 14 has symmetrically fixed first rotating rods 15 on both sides, and the length of the first rotating rod 15 is less than the length of the sliding frame 8. This design ensures that the first rotating rod 15 will not interfere with the sliding frame 8 during rotation, thus ensuring the smoothness of the transmission process. Each first rotating rod 15 is rotatably equipped with a second rotating rod 16, and one end of the second rotating rod 16 is rotatably connected to the slider 9. When the second gear 14 rotates, the first rotating rod 15 will rotate around its axis as the second gear 14 rotates. Since the first rotating rod 15 and the second rotating rod 16 are rotatably connected, the circular motion of the first rotating rod 15 will drive the second rotating rod 16 to perform a complex swing motion. Since the second rotating rod 16 is rotatably connected to the slider 9, the swing motion of the second rotating rod 16 will be converted into the linear sliding of the slider 9 in the sliding frame 8, effectively transmitting the rotational power of the second gear 14 to the slider 9, thereby realizing the adjustment of the height of the harvester blade 1.

[0036] Finally, see Figure 4 and Figure 5In this embodiment, the angle adjustment assembly 12 includes a mounting angle plate 17, which is fixed to the side of the mounting plate 2, providing a mounting base and support point for the entire angle adjustment assembly 12, so that it can be stably connected to the mounting structure of the harvester blades. The support plate 18 at the bottom of the mounting angle plate 17 further provides a support platform for the rotating parts, ensuring the stability of each rotating rod during the movement.

[0037] The first rotating rod 19 is Z-shaped and is rotatably mounted on the support plate 18. This special Z-shaped design can change the direction and stroke of force transmission, enabling more flexible angle adjustment within a limited space. The connecting frame 20 at the top of the harvester 1 is rotatably connected to the first rotating rod 19. When the first rotating rod 19 rotates, it will drive the harvester 1 to rotate around the connection point through the connecting frame 20, thereby realizing the adjustment of the angle of the harvester 1.

[0038] The hydraulic rod 21 is mounted on the support plate 18 and is the power source for the entire angle adjustment assembly 12. The hydraulic rod 21 has the characteristics of large output force and high control precision, and can accurately control the extension and retraction length according to actual needs. A second rotating rod 22 is rotatably mounted on the hydraulic rod 21, and the second rotating rod 22 is rotatably connected to the first rotating rod 19. When the hydraulic rod 21 extends or retracts, it will push the second rotating rod 22 to move. The movement of the second rotating rod 22 will be converted into the rotation of the first rotating rod 19, thereby driving the harvester blade 1 to achieve angle adjustment.

[0039] Working principle:

[0040] When using this harvester blade height and angle adjustment device, the motor is first started according to the actual height of the crop. The motor output shaft drives the first gear to rotate. Since the first gear meshes with the second gear, and the number of teeth of the second gear is greater than that of the first gear, the second gear rotates at a lower speed while obtaining greater torque. The first rotating rods on both sides of the second gear rotate in a circular motion, which drives the second rotating rod connected to it to swing. The second rotating rod pushes the slider to slide within the sliding frame. The slider drives the sliding column to move up and down within the bearing column through the connecting block, thereby adjusting the height of the harvester blade.

[0041] When the angle of the harvester needs to be adjusted due to different terrain or crop growth conditions, the hydraulic rod of the angle adjustment component is activated. The hydraulic rod extends and retracts, pushing the second rotating rod mounted on it to move. The second rotating rod is rotatably connected to the first rotating rod in a Z-shape. The movement of the second rotating rod causes the first rotating rod to rotate around its fulcrum. The first rotating rod is rotatably connected to the top connecting frame of the harvester, driving the harvester to rotate around the connection point, thereby achieving the adjustment of the harvester angle.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
